Abstract

The invention relates to a luminescent unit comprising a luminescent plane, a shell, a light emitting diode module and a light-guide element. The shell has an opening and an emergent light side, wherein the opening is substantially parallel to the luminescent plane. The light emitting diode module has at least one light emitting diode and a circuit board eclectically connected with the light emitting diode, wherein the light emitting diode module is positioned at the side opposite to the emergent light side of the shell. One end of the light-guide element is arranged relative to the opening, and the other end thereof is adjacent to the light emitting diode. The invention can increase the service life and the heat-dissipation efficiency of the luminescent unit.

Description

technical field [0001] The invention relates to a light emitting unit, in particular to a light emitting unit using a light emitting diode as a light source. Background technique [0002] With the advancement of technology, people have also developed more diverse light-emitting units. In general, the light-emitting unit can be a lighting device, an outdoor display board, a light source of a projector, or a backlight module of a flat-panel display device. [0003] Please refer to FIG. 1, taking the backlight module as an example of a light-emitting unit, the conventional light-emitting unit 1 at least includes a front frame 11, a back plate 12, a plurality of light-emitting diode modules 13 and an optical film set 14. Wherein, an accommodating space S is formed between the front frame 11 and the back plate 12 1 . The light-emitting diode module 13 is set in the accommodating space S 1 , and each LED module 13 has a plurality of LEDs 131 and a circuit board 132 for drivin...
